Durable fixation

edilon)(sedra EBS (Embedded Block System) is a durable ballastless track construction system for Metro and Heavy Rail. This prefabricated “block” system is ideally suited for quick and accurate installation in tunnels and stations.

It combines a traditional rail fastening system with the “embedded block technology” from edilon)(sedra. This robust, waterproof track system, has become a standard solution for tunnels and stations.


EBS – designed to save you time and money
Experience effortless and rapid installation with simplified and easy
construction site logistic thanks to space-saving and weight-optimized
EBS design, especially when building tracks in tight spaces such as in
tunnels. You have the flexibility to select your preferred type of rail, rail
inclination, rail fastening clips and system elasticity.

Durable, waterproof bonding
Experience the superior durabel bond of the EBS-system within
the concrete slab, creating an impenetrable barrier against the
intrusion of water, liquids and debris. This ensures the long-lasting
performance of your track system, especially with regard to electrical
insulation, elasticity, acoustic effectiveness and strong mechanical
connection to the ballastless track supporting concrete layer.

edilon)(sedra EBS

EBS basically consists of prefabricated concrete blocks that are elastically and durably fixated in a specially designed concrete tray. The “block tray” combination is quick and easy to install.

This track construction system absorbs a significant portion of the mid- and high-frequency vibrations caused by wheel-rail interaction. In this way, noise emission is also greatly reduced. Not unimportant in urban areas.

Why opt for EBS

  • Durable, waterproof bonding
  • Maximum electrical insulation, important in damp environments such as tunnels
  • Provides stability in straight and curved track sections
  • Easy construction, also as a switch solution
  • No tie bar required, making emergency evacuations safer and faster
  • Complies with EN 13481-5 and EN 13230-3 standards

Track Life Extension

with EBS-RF (Embedded Block System-RetroFit)

edilon)(sedra EBS-RF is a quick-to-install, reliable retrofit solution for worn-out “booted (bi-)block” track structures. The basis of this system consists of a block-forming concrete element with integrated elastic tray, prefabricated as a whole under controlled conditions. After removing the worn or old blocks, empty pockets are created into which the EBS-RF blocks can be easily and quickly installed.


Remove worn or old rubber booted blocks
After the old/worn-out rubber booted blocks habe been
removed, the existing concrete slab structure can be utilized,
which eliminates the need for any drilling or demolition,
ensuring a hassle-free installation.

Positiion EBS-RF unit
The system is supplied as complete prefabricated, including concrete block,
elastically supported tray and fastening clips, ready for immediate application
and quick installation: Without causing any major disruption to train operations,
the track is ready for running train vehicles again just a few hours after the
EBS-RF system has been installed and the mortar has been poured. By this
solution and method, using EBS-RF, the old track system can be refurbished
during the common underground closure period of just 3-4 hours only.

Durable fixation
Ensure long-lasting stability with the rapid bonding of the new EBS-RF
unit into the existing recess using our fast-curing mortar. Our experts
of the EBS competence center stays at your service for a smooth and
quick replacement process of your track - job done!

Very strong adhesion, completely waterproof!

  • Extended service life of the main track structure
  • Uses the existing concrete slab structure; no drilling or demolition of the existing slab structure is required
  • Waterproof system, maximum electrical insulation
  • Significant reduction in future maintenance costs
  • Short (overnight) replacement periods – no or limited track unavailability
